public final class InitSyntax
extends PrefixSyntax

This class implements init syntax.

init <expr>

This type of expression is only valid inside a class initialiser function. The right hand side expression must be an apply expression, which is applying a parent class initialiser. It only makes sense to be able to call an initialiser for each class once, i.e. you can't call different initialisers for the same parent class inside a given initialiser.
